Here we would like to present interconnection between the structural parameters gained by theoretical approaches with the experimentally accessible data. Especially, we focus on the indirect spin-spin 13C-13C interaction constants, that represent unique source of information on the electron distribution within involved atoms and reflect the carbon-caron bonding environment as the measurement of the nJ(C-C) at natural abundance became feasible using the modern NMR instruments in a reasonable time. The theoretical prediction of the nJ(C-C) coupling constants was done using DFT calculation (B3PW91/6-311++G(d,p)) which provides an excellent agreement with the experimental values. The experimental values are further correlated to the carbon-carbon bond lenghts and angles, that are accessible by single crystal X-ray crystallography.
